GRGE is one of the plain-text IPL sections, introduced with San Andreas. It replaces the previously used opcodes 0219, 03BB and 057A. It creates an invisible cube which interacts as a garage. Each garage can be used differently, for example by the script.

Notes
Garage doors are very important for the camera rotation. They control how the camera moves after you have entered a garage. If your camera moves wrong, then simply rotate the pivot of your garage door, map the new one and rotate it until it fits with the rotation you want. Then test if the camera moves correctly in-game.
If you have not mapped a garage door the camera will move to the west, which corresponds to a garage door rotation of 0 degrees around the z axis.
